$Language is a list of strings which give the names of languages to use for messages.

$ScriptCommandLine is a list of strings giving the elements of the command line with which the standalone Mathematica script was invoked.

The following graph represents an impulse response of an ideal Low Pass Filter (LPF). This graph illustrates some of the ways of interacting with graphics. Details on each ...

Mathematica usually works by taking whatever input you give, and then processing it. Sometimes, however, you may want to have a program you write explicitly request more ...

Expressions corresponding to cells. Here is a notebook containing a text cell and a Mathematica input cell. Here are the expressions corresponding to these cells.

It is always a good idea to give variables and functions names that are as explicit as possible. Sometimes, however, such names may get inconveniently long. In Mathematica, ...

As discussed in "Exact and Approximate Results", Mathematica can handle approximate real numbers with any number of digits. In general, the precision of an approximate real ...

ArrayPlot[array] generates a plot in which the values in an array are shown in a discrete array of squares.
